What is the sum of areas of the faces on a rectangular prism called
Answer:
The surface area of the rectangular prism.
Step-by-step explanation:
The formula for the surface area of a rectangular prism is SA = 2 (wl + hl + hw), which actually represents the areas of each of the faces.
SA = 2wl + 2hl + 2hw
We see that the SA is the sum of the areas of the faces on a rectangular prism. Look at a picture of a rectangular prism if you have trouble understanding this.
b) What is the probability of scoring a total of 6?
c) What is the probability of scoring a total greater than 10?
Answer:
b) 16.67%
Step-by-step explanation:
c) 1/5. Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.

The volume of a cylinder varies jointly as the square of the radius and the height. If the volume is 28pi cubic inches when the radius is 2 inches and the height is 7 inches, find the volume
when the radius is 12 inches and the height is 11 inches. Express the answer in terms of pi .
A. 1,728x in
B. 529x in
O C. 1,584x in
D. 1,331x in
Answer:
1584 cu in.
Step-by-step explanation:
Since the volume varies jointly with the radius and height we have an equation V = kr^2h where k is the constant of variation
28 = 2^2(7)k = 28k
k = 1
Now V = r^2h
V = (12)^2(11) = 144(11) = 1584 cu in.

A chicken and rice recipe is shown below. Mrs. Hughes would like to make only two-thirds of the recipe. How many cups of each ingredient does Mrs. Hughes need? 2 2/3 cups of chicken broth 1 1/2 cups of chicken 3/4 cups of rice
Answer:
See explanation below
Step-by-step explanation:
This is actually pretty easy to explain, and we all need to do is work with fractions.
So we have a recipe for chicken and rice, but the person decides to use 2/3 of the recipe. to determine the quantity of each ingredient to be used, we just need to multiply the cups of each ingredient by 2/3, and that's it.
Let's go with each ingredient, one by one:
Chicken broth 2 2/3 cups:
In this case, let's convert the 2 2/3 to a simple fraction. (We just multiply the denominator by the single number and then, sum the numerator)
2 2/3 = (3*2) + 2 / 3 = 8/3 of cups
8/3 * 2/3 = 16/9 cups of chicken.
But to do this better, let's convert this into a mix fraction:
16 : 9 = 1 and the rest is 7 so:
1 7/9 cups of chickenChicken 1 1/2 cups:
We'll do the same thing as before:
1 1/2 = (2*1) + 1 / 2 = 3/2 of cups
3/2 * 2/3 = 1
1 cup of chicken3/4 cups or rice:
3/4 * 2/3 = 1/2
1/2 cup of riceHope this helps

Faiz's total online shipping bill comes to £45.71.
He then receives discount of £15.90.
How much does he have to finally pay after the discount?
£15.9
Solution
Shipping bill = 45.71-15.90=29.81
Hence he have to pay after Discount is 29.81
Given:
Faiz's total online shipping bill comes to £45.71.
He then receives discount of £15.90.
To find:
How much does he have to finally pay after the discount?
Solution:
We have,
Amount of bill = £45.71
Discount amount = £15.90
Now,
Final payment = Amount of bill - Discount amount
= £45.71 - £15.90
= £29.81
Therefore, Faiz's have tp pay £29.81 after discount.

Rotate shape A 180 about point (1,0)
The point after which shape A is rotated 180 degrees is (-1, 0).
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
Shape A is in the point (1, 0).
This means,
Shape A is in the First Quadrant.
Now,
Shape A is rotated 180 degrees.
If rotated clockwise or counterclockwise shape A will be in the same quadrant.
This means,
Shape A will be in the Third quadrant.
Now,
First quadrant coordinates = (x, y)
Third quadrant coordinates = (-x, -y)
So,
(x, y) → (-x, -y)
(1, 0) → (-1, 0)
Thus,
Shape A will be in (-2, 0).

1 Suppose you have a checking account, but you're overdrawn a bit, and your balance is currently - \$ 250 . 25−$250.25. You incur another charge on the account, which decreases your balance by \$ 101 . 33$101.33. How much money do you need to bring your account balance back to \$ 0$0?
Answer:
$351.58
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Current balance = -$250.25
Other charge (debit) = $101.33
So, Now the current balance in the account are as follows,
Current balance = - $250.25 + (- $101.33) (debit is negative)
Current balance = -$250.25 -$101.33
Current balance = -$351.58
So, we need $351.58 to bring account balance to $0.
